Abstract (en)
A character pattern converting circuit (3) is adapted to control a character pattern expressed in the form of a dot matrix and received from a character generator (2) and to deliver the character pattern so converted, and includes a first switching circuit (7) for switching the order of bits constituting the character pattern provided from the character generator (2); a matrix circuit (8) having shift registers (10 to 17) arranged in the form of a matrix, the shift registers (10 to 17) being adapted to shift upon permitting the character pattern from the first switching circuit (7) to be entered in succession in the row or column direction thereof and to be delivered in the row direction thereof, respective bits of the character pattern simultaneously or selectively in conformity with the mode of the concerning conversion; a second switching circuit (9) for switching the order of the bits constituting the character pattern provided from the matrix circuit (8) in conformity with the mode of the concerning conversion; and a matrix control part (6) for controlling the writing of the character pattern into the matrix circuit (8) via the first switching circuit (7) and the reading of the character pattern from the matrix circuit (8) via the second switching circuit (9).
